Traditional pipeline connection methods mainly include welding, threaded connection, flange connection and clamp connection, etc. These methods mostly rely on the cooperation of sealing materials, and the sealing performance directly affects the safety and reliability of the pipeline system. However, in some special scenarios, traditional connection methods have many problems, especially in environments with strong fluid scouring, corrosion or severe temperature changes, the sealing performance of the pipeline connection part is easily damaged, leading to leakage, corrosion and even pipeline rupture and other serious consequences.
